I Recently Took C4 Which Is A Pre Workout Supplement.

I recently took C4 which is a pre workout supplement. I have noticed discoloration in my urine after taking it, but figured it was dehydration so I have been drinking lots of water. Today, my urine appears red and seems like it is blood. What could be causing this?
